TENSION-REGULATING DEVICE FOR AUTOGRAPHIC REGISTERS.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed September 11, 1905. Serial No. 277,983.

To all whom it may concern:

Be it known that I, ENGLAND J. BARKER, a citizen of the United States, and a resident of Morgan Park, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Tension-Regulating Devices for Autographic Registers, of which the following is a full, clear, and exact description.

Heretofore one of the difliculties it wasdesired to overcome in operating autographic registers employing one or more rolls of paper was due to the tension or pressure it was necessary to apply to them to prevent the paper from unwinding orpaying out too fast. With the means now in use the tension is the same whether the roll is large or small, with the result that when the roll is large the paper can be withdrawn from the machine without the resistance of the tension devices being appreciably felt, because the leverage from the center to the circumference thereof is greater; but as the roll becomes reduced in diameter, the leverage exerted thereon being less, the relative resistance of the tension devices is greater and there is a constant liability of the paper tearing in the machine.

It is the object of my invention to avoid this objection by automatically regulating the said tension so that the resistance to the paying out of the paper from the rolls will be the same at all times and will not interfere with its withdrawal from the machine or cause it to tear. This I accomplish by the means hereinafter fully described and as particularly pointed out in the claims.

In the drawings, Figure 1 is a side elevation of an autographic register having my improvements applied thereto. Fig. 2is a transverse vertical section thereof, taken on dotted line 2 2, Fig. 1. Fig. 3 is an elevation of a portion of the machine looking outward at one of said tension devices from the inside of the machine. Fig. 4 is a perspective view of said tension-regulating device segregated from the remainder of the machine and drawn to a larger scale. Fig. 5 is a section similar to that shown in Fig. 2, showing a modified form of my tension-regulating device. Fig. 6 is an inside elevation of said modified form of tension-regulating device drawn to a larger scale.

Referring to the drawings, A represents the base-plate of an autographic register, and B is the stationary, and C the hinged, sections thereof. Section B consists of longitudinal vertical side walls, permanently secured to the base-plate, which have their rear portions very much reduced in height and their forward portions arising to very near the full. height of the machine and connected at the front of the machine by a suitable end plate. The frame of section C consists of longitudinal side walls, which are united at their rear ends by a suitable end plate and have their upper edges connected by a bed-plate or platen forming a portion of the topof the machine. The rear portions of the sides of section C extend down from the platen such a distance that when said section is closed over section B its lower edges will rest upon the upper edges of the reduced rear portion of the sides of section B, and the forward portion of the sides of section C depend downward from the bed-plate thereof but a slight distance to enable them to rest upon the upper edges of the higher forward portions of the sides of section B under like conditions. Section C is hinged at its lower rear corners to the rear ends of the sides of the section B, and when closed down over said section B it is locked in its closed position by means of a hinged frame D, hinged to the upper forward ends of the vertical sides of section B. I do not wish to be confined to the construction of the frame work of the register as hereinbefore briefly described, however, because my improvements could be applied to autographic registers differently constructed and differently designed.

In the autographic register illustrated in the drawings the rolls of paper a a and b are used that have cores of pasteboard or other material, which are journaled in or on stationary centering-bosses c c on one side of the machine (which may revolve on their centers, if desired) and in or on laterally-movable bosses or centering-plates E at their other ends next the other side of the machine. Centering-plates E are secured to vertically-disposed arms F F and horizontal arm G. The lower ends of arms F are bent toward the sides of the machine and pivoted in the lower ends of vertically-disposed boxes G, extending from the bottom to the top of the sides of the higher forward portions of the section B of the machine. Pivotally secured to lugs projecting from the side of arms F F, preferably at points below the plane of the centering-plates, are levers H, which extend upward and are bent toward the center of width of the machine and pass through vertical slots f bolt.

in the upper portions of the said arms above the centering-plates, as shown. At a point about in alinement with the axis of the roll of paper, levers H each have the inner end of a ho t g pivoted thereto, which latter extends laterally into a short tubular pocket g and out through the outer end thereof and is provided ,with a head it, the screw-threaded shank 01 which permits it to be adjusted to the extent desired in the outer end of said A coil-spring I surrounds bolt 9 between the lever H and the outer end of the pocket g and keeps the lever normally pressing inward.

In operation when the roll of paper is inserted in the machine the upper ends of arms F, which extend slightly above the plane of the upper edges of the sides of section B, are drawn outward, so as to permit of the rolls of paper being placed between the two sides of said section and centered on the stationary boss on one side and the centering-plate carried by said arms on the other side. The diameter of the roll being greater forces the upper ends of the lever H outward and compresses the spring. As the paper on the rolls is played out and its diameter becomes less the lever automatically moves inward toward the center of the machine, and thus causes the spring to expand and its pressure upon the arm F to become weaker as the diameter of the roll of paper becomes less and less. Arms F can be manipulated from the outside of the machine through the medium of bolt 9.

The box F for the roll of paper journaled in the hinged. section C of the machine is preferably horizontally disposed and extends from the vertically-disposed ed e of the sides of said section connecting the lower edge of the deeper portion of said sides and the shallower portion. Arm G, lever H, and the spring are all horizontally disposed and are arranged and cooperate the same as those used in connection with the other section of the frame of the machine. I

In Fig. 5 of the drawings I show a modified form of my invention. In this modification the arm J and the centering-plate j, carried thereby, are the same as those hereinbefore described. The lever K, however, is hinged at its up er end to or between lugs projecting outwardIy from said arm J and extends downward and inward at a suitable angle through a vertically-elongated slot 7c in arm J below the centering-plate. A flat spring M is secured at its lower end to the outer wall of the box near the bottom thereof, and the u per end of this spring presses against lever I and kee s it normally pressing toward the center of t e machine. In order to permit of the manipulation of the arm J from the outside of the machine, I secure a bolt L to the same near its upper end, which bolt'extends laterally outward through the slotted opening near the upper end of the box and has its outer end headed. The operation of this modification is'identically the same as that of the tension-regulating devices first described, and that is to say as the roll of paper diminishes in diameter the lever moves inward, and thus causes the tension of the spring to be exerted upon the arm J to be less and less as the size o1 the roll decreases, and thus by decreasing the tension of the spring compensates for the decreasing leverage of the roll of paper as it pays out.
